Quality Control

Every batch of our L-Alanine, L-Tyrosyl-L-α-Glutamyl-L-Glutaminyl-L-Leucyl-L-Arginyl-L-Asparaginyl-L-Seryl-L-Arginyl- (9Ci) is manufactured under controlled conditions and undergoes rigorous analytical testing to ensure the highest standards of purity and identity. Our quality assurance protocol includes advanced techniques such as HPLC, MS, and NMR for comprehensive characterization. A detailed Certificate of Analysis (COA) documenting purity, identity, and other critical parameters is provided with each shipment to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a freezer. This product is hygroscopic (moisture-sensitive) and should be allowed to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake. For long-term storage, consider storing under an inert atmosphere.
